OK well i have a Linksys wireless-G 2.4 GHz router connected to my modem, and well the modem connects to the wireless router and then the router brings a cable to the desktop and give off the wireless signal right. well my wireless in my house is working like my iPod touch is recieving a signal and everything but my desktop which is directly connected to the router isn't receiving a signal. Everything says its connected. when i try to sign into msn on the desktop it says i have a problem with my DNS. But when i connect directly from the modem to the desktop everything works fine. Any suggestions on what this might be and how i can fix it?
